Answer:
Step-by-step explanation:
tan61=FD/24
FD=24tan61
tan19=DE/FD
DE=FDtan19, since FD=24tan61
DE=(24tan61)(tan19) (exact)
DE=14.9 units (rounded to nearst tenth)
Though they might round to 15 units...
Answer:
12
Step-by-step explanation:
if we know we want a profit of at least 114, we need to solve for x.
if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.
-0.5(12)^2 + 25(12)-111 = 117
Answer:
I dont know if this is supposed to be solved a certain way for a class, but as a bargain shopper, this is what I would do to figure out the best value.
Step-by-step explanation:
First divide $10 by 4: 10.00/4=2.5 or $2.50 per card
Then, divide $14 by 6: 14.00/6=2.3333333 so about $2.33 per card
Now, just look at the two answers and see which one is less.
If you buy 4 cards for $10, you will pay $2.50 for each card and if you buy 6 cards for $14, you will pay about $2.33 for each card. Therefore, the better value would be the 6 cards for $14.
<em>Angle </em><em>ADG,</em><em> </em><em>angle</em><em> </em><em>BEH </em><em>and </em><em>angle</em><em> </em><em>CFI,</em><em> </em><em>all </em><em>have </em><em>two </em><em>curves</em><em> </em><em>in </em><em>their</em><em> </em><em>angles</em><em>.</em><em> </em><em>Same </em><em>number</em><em> of</em><em> </em><em>curves</em><em> </em><em>are </em><em>used</em><em> </em><em>to </em><em>represent</em><em> </em><em>that </em><em>their</em><em> </em><em>measure</em><em> </em><em>are </em><em>equal</em><em>.</em><em> </em>
So, m angle CFI = m angle ADG
So, m angle CFI = m angle ADG=> m angle CFI = 92°
First, convert both fractions into improper fractions:
-2 and 1/4= -9/4
-4 and 1/2= -9/2
Now we can find the product!
-9/4 x -9/2= 81/8
(Remember that when you multiply two negatives, the product turns positive)
And because 81/8 cannot be reduced, to find your final answer, just covert 81/8 into a mixed fraction!
81/8= 10 and 1/8
Hope this helps!
